Dibutylamine → HCID 71062377, 화합물

To a solution of methyl 4-(2-chloropyrimidin-4-yl)-3-(1,2,3,4-tetrahydroisoquinoline-2-carbonyl)benzoate (82 mg, 0.20 mmol) in DMF (1.0 mL) were added dibutylamine (Aldrich, 52 mg, 0.40 mmol) and potassium carbonate (83 mg, 0.60 mmol). The reaction mixture was heated at 60° C. for 5 h and 80° C. for 3 h. After cooling to room temperature, the reaction mixture was quenched with cold water. The mixture was extracted with EtOAc (3×). The combined organic extracts were dried over MgSO4, filtered and concentrated in vacuo to give the title compound (69 mg, 95%). MS (ESI+) m/z 501.2 (M+H)+.
